You can block domains from receiving emails. Previously you could find only a list of blocked emails. Sometimes there can be different email addresses with the same domain, so it’s better to block the entire domain. Go to My Account > Settings > Email Settings. Click on Blocked Email Domains to see the list of blocked domains.
To add a domain to the list, click on Block Domain button. Enter the Domain Name and the relevant Notes for the same. Click on Save.
To unblock an email domain, hover your cursor over the settings icon, and click Unblock.
